Operation

8.1

Operating instructions

Observe the following points when operating the device:
— Aggressive media may result in corrosion and abrasion of
the parts that come into contact with the medium. As a
result, pressurized media may escape prematurely.
— Wear to the flange gasket or process connection gaskets
(e.g., aseptic threaded pipe connections, Tri-Clamp, etc.)
may enable a pressurized medium to escape.
— When using internal flat gaskets, these can become
embrittled through CIP/SIP processes.
If there is a chance that safe operation is no longer possible,
take the device out of operation and secure it against
unintended startup.
